Fast mean and variance computation of the diffuse sound transmission through finite-sized thick and layered wall and floor systems KU Leuven
© 2018 Elsevier Ltd A method is developed for computing the mean and variance of the diffuse field sound transmission loss of finite-sized layered wall and floor systems that consist of solid, fluid and/or poroelastic layers. This is achieved by coupling a transfer matrix model of the wall or floor to statistical energy analysis subsystem models of the adjacent room volumes. The modal behavior of the wall is approximately accounted for by ...
